[A study of dietary intakes and dietary preferences by questionnaire at a health facility in an urban area].

Dietary preferences and intakes of 2504 patients in a human dock in Tokyo were studied by questionnaire and analyzed according to: 1. Comparison of dietary patterns for breakfast to that for lunch and dinner. 2. Consistency between dietary patterns according to Category Score Table for Breakfast and that from Hayashi's Quantification Theory Type III (QIII). Dietary patterns for breakfast were shown to fall into four Types based on dietary intakes and dietary preferences: Balanced Diet-Japanese Style (Type 1); Balanced Diet-Western Style (Type 2); Unbalanced Diet-Western Style (Type 3); and Unbalanced Diet-with drinks (Type 4). Based on the responses to the questionnaire, there was no correlation between the dietary pattern for lunch to that for breakfast. On the other hand, the dietary pattern for dinner tended to correlate with breakfast. The sample population was divided into two random groups A and B. Group A was analyzed by QIII, and B by the four types of breakfast dietary patterns. Comparison of scores for categorized values for Group A with those of the Group B indicated 91.8% consistent rate. These results, demonstrate that this questionnaire can be used effectively to sort intakes into four dietary patterns, and may be useful in preventive health care studies.

Relation of food consumption to cancer mortality in Japan, with special reference to international figures.

The present study was designed to examine the epidemiological association of food consumption with cancer mortality in Japan, if any, in comparison with similar examinations in developed countries including Japan, in a search for dietary factors in cancer etiology. Whereas food consumption patterns in Japan was believed to be specific among developed countries, this study revealed that the correlation matrix among major foods both for international and Japanese data made it possible to categorize these foods into two groups with some similar patterns, since there should be observed a positive or negative correlation for each pair of foods. The patterns for correlation of food consumption to cancer mortality in Japan were found to be considerably different from those in developed countries, and this suggested that the epidemiological association between the two in Japan, if any, could be specifically evaluated from that in develop countries. The urban-type region for food consumption in Japan, however, indicated a possible westernization for the relation of food consumption to cancer mortality as well as for food consumption patterns, whereas the traditional Japanese region for food consumption did not indicate any similarity with westernization for the relationship between food consumption and cancer mortality, as well as for food consumption patterns. The above findings also suggested that there might be a possible significance for the regionalization of Japan in such studies, and that the urbanization of food consumption patterns in Japan would show that this country has a similar pattern of association between food consumption and cancer mortality as observed among developed countries in Europe and/or North America.

Man, fish, and mercury on small islands in Japan.

This paper examines the differentiating patterns of subsistence activities, fish-eating habit, mercure level in human biological specimens, and the interrelation among these variables on several small Japanese islands. The catch and supply of fish vary according to patterns of division of labour on each island. The frequency of fish-eating is generally regulated by the availability of fish, and is well associated with the level of mercury in hair or red cells. Difference in variety of fish consumed has a modifying effect on the mercury level. The importance of understanding the total ecological setting relating to any environmental problem should be emphasized.
